SPOLIERS WARNING (if you could count them as spoilers) Silver cove is the place to get Lugia, if you played the Pokémon Soul Silver or Pokémon Silver hence the name, Lugia will come out of the waterfall and approaches the player on the shrine. Cragonos Spring is unknown still, it's probably a place where mewtwo is going to be at. Much like the Pokémon Origins show where Red met Mewtwo in a blue cave filled with crystals.
